Abstract

An object of the present invention is to prevent breakage of a connector or a board due to insertion / removal of a plug connector without requiring fixing work on a board outer edge side. A connector includes a connector body, a shell fixing terminal, and a hook. The shell fixing terminal 15 is formed in a V-shape in which a tip is separated, and has a spring force in a direction in which each leg forming the V-shape opens. Each leg of the V-shape is held in a state of being closed with solder before mounting the board. The connector 11 is inserted into the hole 4 so that the hook tip of the hook 16 does not catch on the substrate 4. When the solder with the legs closed is melted by reflow heating the substrate 4 on which the connector 11 is mounted, the legs are opened, and the spring fixing force fixes the shell fixing terminal 15 to the hole 7 and slides the connector 11 to catch. The hook 16 is hooked on the outer edge of the substrate.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connector mounted on a substrate incorporated in an electronic device, and more particularly to a connector structure for preventing a connector or a substrate from being damaged by a plug connector of an external device.

[0002]

2. Description of the Related Art FIG. 7 is a schematic structural view showing a conventional connector mounted on a board incorporated in an electronic device, and FIG. 8 is a longitudinal sectional view showing the conventional connector mounted on the board. FIG. Connector 1 has connection pin 2
Are formed by a socket connector 3 disposed therein and a shell fixing terminal 5 provided on a surface of the socket connector 3 facing the substrate 4. The shell fixing terminal 5 is arranged from the center of the board of the socket connector 3. A lead terminal 6 is formed on the other end of the connection pin 2 for electrical connection with the substrate 4, and is soldered together with the shell fixing terminal 5 inserted into the hole 7 of the substrate 4. Surface mounted. The connector 1 is usually arranged on the outer edge of the board 2 so that the plug connector of the external device can be easily removed.

A user connects an external device to an electronic device by inserting a plug connector of the external device into the socket connector 3, and removes the external device from the electronic device by removing the connected plug connector from the socket connector 3. . Since the connector 1 is fixed by the shell fixing terminal 5, the plug connector can be removed without any problem.

[0004]

However, when the plug connector 8 is removed from the conventional connector attached to the board, the connector 1 is not fixed on the outer edge side of the board, so that the connector 1 is removed as shown in FIG. The outer edge side of the board of the connector 1 is lifted by the operation, and the solder to which the lead terminal 6 is bonded may be peeled off, cracked, or the shell fixed terminal 5 or the board 4 may be damaged.

In this case, it is conceivable to fix the outer peripheral side of the connector 1 to the substrate 4 using a jig, but another component called a jig is required separately. Further, even if the socket connector 3 is integrally formed with the jig, an operation for fixing the connector 1 to the substrate, such as screwing, is separately required.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and an object of the present invention is to prevent damage to a connector or a board due to insertion / removal of a plug connector without requiring fixing work on the outer edge side of the board. It is an object of the present invention to provide a board mounting connector having a structure which can be performed.

[0009]

Preferred embodiments of the present invention will be described below with reference to the drawings. The same components as those in the conventional example are denoted by the same reference numerals.

FIG. 1 is a schematic configuration diagram showing an embodiment of a board mounting connector according to the present invention, and FIG. 2 is a longitudinal sectional view showing the board mounting connector mounted on a board. FIG. 3 is a longitudinal sectional view showing the board mounting connector fixed to the board. Board mounting connector (hereinafter simply referred to as “connector”) 11 in the present embodiment
Is formed by a connector body 12, shell fixing terminals 15, and hooks 16. The connector body 12 is
The socket connector 3 for detachably connecting a plug connector 8 from an external device is a main part, and has a box-shaped appearance. Since the socket connector 3 is a portion into which the plug connector 8 of the external device is inserted / extracted, the connector 11 is provided with a board so that the plug connector can be easily inserted / extracted from the outside of the housing of the electronic device (not shown) including the substrate 4. 4 is disposed on the outer edge. The connection pin 2 is provided inside the socket connector 3, and the other end of the connection pin 2 is
Lead terminals 6 are formed for electrically connecting the board 4 and an external device connected to the socket connector 3, and are surface-mounted by soldering.

The shell fixing terminal 15 which is a feature of this embodiment is provided on the surface of the connector main body 12 facing the substrate 4 and protrudes near the center side of the connector main body 12 on the substrate. The arrangement of the shell fixing terminals 15 in the connector 11 is the same as in the related art. The shell fixing terminal 15 has the hole 7
The connector 11 is fixed to the board 4 by a spring force that expands in the width direction when the connector 11 is inserted into the board 4. The shell fixing terminal 15 in the present embodiment is formed in a V-shape in which the tip is separated, and each leg forming the V-shape is urged in the opening direction. Although details will be described later, when the connector 11 is mounted on the substrate 4, each leg forming a V-shape as shown in FIG. 2 is compressed by the solder 17 as shown in FIG.
It is fixed in a closed state. In addition, the hook 16 which is another feature of the present embodiment is formed by extending the surface of the connector body 12 facing the substrate 4 toward the outside of the electronic device and bending the tip of the hook into a hook shape. You.

Next, the connector 11 according to the present embodiment will be described.
The procedure for attaching the to the substrate 4 will be described.

In this embodiment, it is necessary to perform an operation of closing the legs of the shell fixing terminal 15 before attaching the connector 11 to the board 4 for the first time. With the legs open,
This is because the shell fixing terminal 15 cannot be inserted into the hole 7.

FIG. 4 is a view showing a state in which the connector 11 is placed on a device for closing the legs of the shell fixing terminal 15 which is normally opened in a V-shape by soldering. This device includes a base 18 and a slide base 19.
have. As shown in FIG. 5, when the connector 11 is placed so as to span the tables 18 and 19, the connector 11 slides the slide table 19 in the direction of arrow A. Thereby, each leg of the shell fixing terminal 15 is pressed down as shown in FIG. In this state, the solder supply arm 20 is guided to the position of the shell fixing terminal 15, and then the automatic soldering iron 21 is pressed against the tip of the solder supply arm 20. Thus, the solder supplied by the solder supply arm 20 is melted. When each leg of the shell fixing terminal 15 is covered with the melted solder, the automatic soldering iron 21 and the solder supply arm 20 are retracted. Each leg of the shell fixing terminal 15 is held in a closed state by solidification of the coated solder. Thereafter, the connector 11 is removed from the instrument by retracting the slide table 19.

As described above, preparation for mounting on the board 4 is performed on the connector 11. The pre-preparation process includes placing the connector 11 on the base, sliding the slide base 19, soldering (operation control of the solder supply arm 20 and the automatic soldering iron 21), sliding the slide base 19, and mounting the connector 11 on the base. It consists of a process of removal from the table, but any process can be performed by automatically controlling the machine. That is, the preparation process can be automated. Next, an operation of attaching the connector 11 to the substrate 4 will be described.

First, as shown in FIG. 2, the shell fixing terminal 15 is inserted into the hole 7 and the connector 11 is mounted on the board 4. At this time, if the hook tip of the hook 16 comes into contact with the substrate 4, the connector body 12 floats.
The shell fixing terminal 15 is placed so as to be located on the outer edge side of the substrate of the hole 7. As a result, the hook tips of the hooks 16 do not hit the substrate 4, so that the connector main body 12 can be placed so that the entire surface of the connector body 12 facing the substrate 4 is in contact with the substrate 4.

By the way, in order to allow the connector 11 to be mounted on the board 4 without the hook tip of the hook 16 being hooked on the board 4, the length a of the hook tip is required.
It is important to adjust the diameter of the hole 7 in the same direction as the length a and the thickness of the shell fixing terminal 15 in a state where the legs are closed in the same direction as the length a. That is, when the shell fixing terminal 15 with the legs closed is inserted into the hole 7, the diameter of the hole 7 must be determined so that the shell fixing terminal 15 can be moved more than the length a of the hook portion. In order to achieve the effect as the hook 16, it is desirable that the length a is 0.2 mm or more. Therefore, the diameter of the hole 7 is adjusted with reference to the thickness of the shell fixing terminal 15. In the present embodiment, the hole 7 is formed as a long hole.

As shown in FIG. 2, when the connector 11 is mounted on the board 4, the board 4 is reflow-heated. this is,
It is possible to use not only the connector mounting step but also a reflow heating step that is usually performed.

When the substrate 4 is put into a reflow furnace and heat is applied, the solder 1 with the legs of the shell fixing terminals 15 closed
7 melts and melts down. Thereby, the leg of the shell fixing terminal 15 is opened by its own spring force. Since the legs on the outer edge of the board are placed in contact with the inner wall of the hole 7, the connector 11 moves the board 4 on the board 4 by the pressing force on the inner wall of the hole 7 due to the opening operation of the leg. Slide to the center. As a result, the hook 16 is hooked on the outer edge of the substrate as shown in FIG. When the legs of the shell fixing terminal 15 are fully opened, each leg engages with the inner wall of the hole 7 while abutting and pressing the inner wall of the hole 7. Thereby, the connector 11 is fixed by the shell fixing terminal 15.

According to the present embodiment, the connector 11 can be fixed to the board 4 by the shell fixing terminal 15 and the hook 16 as described above. In particular, in the present embodiment, since the hook 16 for fixing the connector 11 is provided on the outer edge side of the board, it is assumed that a force is applied in a direction perpendicular to the plane of the board 4 when the plug connector 8 is inserted and withdrawn, especially when the plug connector 8 is removed. Also, the outer edge side of the board of the connector 11 does not rise. Thereby, the solder which joined the shell fixed terminal 15 and the lead terminal does not peel, cracks do not occur, and the shell fixed terminal 15 or the substrate 4 is not damaged. Further, in the present embodiment, a spring force is applied to the shell fixing terminal 15, and the connector 1
1 can be attached to the substrate 4.
There is no need to separately prepare a jig or a fixing operation for fixing the connector 11. Further, the operation of attaching the connector 11 can be automated.

[0021]

According to the present invention, since the connector can be securely fixed to the substrate, the solder to which the lead terminals have been joined is peeled off or cracked due to the removal of the plug connector connected to the connector. Or the fixed terminal or the substrate can be prevented from being damaged.

Further, since the fixed terminal is provided with a spring force in the opening direction, the structure is such that the fixed terminal and the hook can be fixed to the board when the connector is mounted on the board. No new installation work occurs due to the arrangement of the hooks.
